CAR-MovEa.

SPECIFICATION forming part of Letters Patent N o. 739,017, datedSeptember 15, 1903.

Application filed December 9, 1902. Serial No. 1341593. (No model.)

To all whom, it may concern.-

Be it known that I, RICHARD MILLER, residing at Appleton, in the countyof Outagamie and State of Wisconsin, have invented a new andusefulImprovement in Car-Movers, of which the following is adescription, reference being had to the accompanying drawings, which area part of this specification'. The object of my invention is to providea novel pinch-bar or car-mover especially adapted for use for startingand movinglimitedly cars on a track.

By my novel construction I secure certain advantages in the constructionof the carmover and also obtain benelits in securing the implement inplace against slipping on the track, on which it is supported when used,and also advantages in the method of applying force to the car-wheel andin securing with the same power greater effort on the carwheel in thedirection of moving the car ahead than have heretofore been obtained..

My invention consists of the car-mover, its parts and combinations ofparts, as herein described and claimed, or the equivalents thereof.

In the drawings, Figure l represents my improved carmover,parts beingbroken away and parts being shown in section for clear illustration ofits construction in connection with a fragment of a car-wheel toillustrate the method of using the implement. Fig. 2 is a top plan viewof my improved car-mover, a. portion of the handle being broken away andomitted. Fig. 3 is a cross-section on line '3 3 of Fig. 2. Fig. 4 is atransverse sect-ion of the front end of the main bar and of thenose-piece or pusher thereon. Fig. 5 represents my improved car-mover inconnection with a fragment of a wheel of a car, the carmover being in aposition which it has when the main bar has been moved down at its outerend in the act of moving a car; and Fig. 6 is across-section similar toFig. 4, showing a different form of construction of the two parts shown.

In the drawings, A represents a fragment of a car-wheel, shown in thedrawings for illustrating the method of using my improved car-mover.Infthe car-mover 2 represents the main bar, which is advisablyconstructed with a socket in its outer end, into which a wood handle 3is inserted, and thereby made a part of the main bar. To the front partof the main bar 2 a fulcrum member 4 is pivoted. For securing these twomembers together properly the member 4 is slotted longitudinally fromits rear end forwardly, and at its rear end the two side pieces of thefulcrum member 4 are pivoted to the bar 2 at a distance rearwardly fromits front ond by a transverse pivot-pin 5. The front end of the main baris thus made free to swing in the fulcrum member. This fulcrum member 4in use is fulcrumed on the rail on which the wheel of the cartravels,and in order to furnish a strong and holding fulcrum-bearing on the railand a fulcrum-bearing ythat shall securely take hold of the rail, whichis usuallys lightly convex on its top surface and also after use issurface-hardened, I provide a fulcrum consisting of square blocks 6 6,which are fitted transversely of the fulcrum member in a recess therefordiagonally in its under surface at a distance rearwardly from its frontend. These fulcrum-blocks consist, advisably, of two members 6 6, Fig.3, iitted into the transverse recess therefor in the fulcrum member atan angle to each other, so that the lower fulcrum edge of these blocksis raised slightly centrally of the fulcrum member, whereby thesefulcrum-blocks are adapted to rest on or bear against the somewhatconvex surface of the rail at two points at least at a little distanceaway from the longitudinal central and raised line of such curvedsurface of the rail. By this means I am able to get a more extendedbearing for the fulcrum-block transversely on the rail,

lthereby better holding it in position on the rail than is obtained whena fulcrum-block having a straight-edge is employed, Vwhich bears only ata single point on the transversely-curved surface of the rail. Thesefulcrum-blocks are conveniently secured in place inthe fulcrum member bybeing locked thereto by wedging-keys 7. 4A steel horn S may be insertedin lthe front end of the fulcrum member 4, which, projecting slightlyabove the surface of the member, furnishesa hard and enduring bearingadapted to contact with the car-wheel and prevent wear of the frontextremity or nose of the fulcrum member. A flat spring. 9 may be placedunder the front end of the fulcrum member and secured thereto by a bolt10. This spring is adapted to lift the front end of the fulcrum memberfrom the rail when the car-wheel moves away from the fulcrum member.

On the front end of the main bar 2 I provide a nose-piece or pusher 11.This pusher is provided with a curved outer surface 12, adapted to fitagainst and thereby to adhere to the peripheral surface or tread of acarwheel and so pivoted on the bar 2 that it is adapted to take theinitial position shown in Fig. 1, and as the main bar is swung down inthe act of pushing against and starting the car-wheel the pusher swingsto the position shown in Fig. 5. I preferably construct this pusher withrearwardly-extending fui-cate arms 13 13, which near their extremitiesare pivoted by a pin 14 to the front end of the bar 2. For strengtheningthe movable connection between the pusher and thebar I advisably providecurved shoulders 15 15 on the bar 2, against which thecorrespondinglycurved extremities of the arms 13 13 it,where by thestrain of pushing the car-wheel comes not only on the pivot 14, but alsoon the shoulders 15.

It will be observed that by reason of the length of the arms 13 theradial distance from the pivot 14 to the surface 12 of the pusher issuch that when it swings on the bar 2 from the position shown in Fig. 1to the position in Fig. 5, while the fulcrum remains in constantposition on the rail, the pusher exerts a forwardly-pushing strain onthe carwheel in the nature of a toggle-joint action, whereby the wheelis compelled to move ahead if the main bar of the car-mover is forceddown.

A cross-strap 16 on the fulcrum member 4 is adapted to engage stop 17 onthe bar 2 when the parts come to the position shown in Fig. 5, andthereby prevent further swing of the fulcrum member on the main bar inthis direction. 1

In Fig. 6 I have shown a form of construction invwhich the pusher 11 ismounted on the bar 2 in a slightly-different form from that shown in theother figures, in that the pusher 11 is provided with a tongue 18, thatfits into a socket therefor in the front end of the main bar and ispivoted to the bar. In this form of construction the tongue may bearmovably against the bar at the bottom of the socket, thus securing theadditional strength required in this connection.

What I claim as my invention is- 1. A car-mover, comprising a main bar,an elongated fulcrum member pivoted at its rear end on the main bar nearits front end and provided medially with a fulcrum-bearng, and a pushermember pivoted on the front extremity of the main bar and adapted byitsfront surface to engage a car-wheel and when the long arm of the mainbar is depressed at its rear end to be lifted and permitted to swingforwardly about the front end of the main bar.

2. A car-mover, comprising a main bar, a fulcrum member pivoted on themain bar at a distance rearwardly from its frontend and providedmedially with a fulcrum-bearing, and a pusher member pivoted in front ofthe pivot of the fulcrum member on the main bar and having a surfacedistant radially from its pivotal connection with the main bar adaptedto bear against and engage a carwheel and on depressing the rear end ofthe main bar to swing toward a right line with the main bar exerting atoggle-joint action therewith. v

In testimony whereof I affix my signature in presence of two witnesses.
